I may not be as qualfied as some of the others on the forum, but I have 4 cats, all whom I added to the household one at a time. Each cat that came home was quarantined for only a couple days. When indroductions came about, we supervised and it took the cats about a week or 2 to get used to each other. But, when I brought home Dot, (she was 1 year), she really picked on my 1st cat for 2 months. Sera (#1) was the alpha cat. Dot was a little younger and a little tougher. They finally got it worked out and now I would say Dot is the alpha cat in out house now. I just made sure Sera never got hurt, but they had to have a few scuffles before Sera relinquished her place in the order. We gave her lots of love and treats to let her know it was okay. There were even times when Dot would get "grounded" to a room if she was really giving Sera a hard time. THe funny thing was Dot was so sweet to Mallory (#3) from the beginning. She would lick her and lay with her, but she didn't like Sera. But, after a couple of months, it was all worked out. Everyone is happy and fine.
Good luck to you. Oh! I almost forgot our biggest secret...we give the cats 1 can of wet food every morning to share. (separate bowls of coarse) I really think feeding them this treat all in the same place with the "human" standing over, taught them all that they are loved and special and eased their stress.
